[sdf] Added total memory allocation log. 

* src/sdf/ftsdf.c (*): Replaced `FT_QNEW' and `FT_ALLOC_MULT'
  to custom macros in order to track memory allocations
  throughout the process of generating SDF. It basically
  add the memory being allocated to a static global variable
  and at the end outputs it at the end.
